Question

Peaks of LH and FSH production occur during

• A. Flow phase of the menstrual cycle
• B. Follicular phase of the ovarian cycle
• C. Period surrounding ovulation
• D. End of the luteal phase of the ovarian cycle

Answer 1

The correct option is C Period surrounding ovulation

Menstruation is the shedding of the lining of the uterus (endometrium) accompanied by bleeding. The menstrual cycle is regulated by hormones. Luteinizing hormone and follicle-stimulating hormone, which are produced by the pituitary gland, promote ovulation and stimulate the ovaries to produce estrogen and progesterone. The follicular phase ends when the level of luteinizing hormone increases dramatically (surges). The surge results in the release of the egg (ovulation) and marks the beginning of the next phase.

So the correct option is 'period surrounding ovulation'.
